The editor is a Ext.form.ComboBox, so i thought this should work but it does not.

My second approach:
I added an listener to my editor (Ext.form.ComboBox), so i could expand my combobox when it gets focus. Again there is no problem of catching the desired event but if i try to expand
the combobox i get the following error:
>>this.list has no properties

I dunno why i get this error. The store of my combobox is autoloaded, so i m pretty sure the list should exist. I tried playin around with mode, lazyRender and loaded the store explicitly but noting helps.
